Background
In the traditional or open process, doctors directly contact the operation part, and the operation incision is relatively large, so that the pain of patients is great, and the postoperative recovery is slow. In minimally invasive surgery, however, the patient is involved in an abdominal or endoscopic surgical procedure, which is performed through a small incision in the patient or a narrow cannula inserted into the incision. Minimally invasive surgery has advantages over open surgery due to its reduced patient trauma, reduced patient recovery period, and significantly reduced overall cost. To accommodate the specific needs of both endoscopic and laparoscopic surgical procedures, endoscopic suturing devices have been developed to provide easy access to the surgical site by the surgeon. Typically, these stapling instruments include an articulatable tool member supported proximate the distal end of the stapling apparatus. The tool component may be selectively manipulated to enable a surgeon to manipulate the surgical device in a confined space. These instruments provide significant medical benefits to endoscopic procedures. Nevertheless, improvements in cost reduction and manufacturing complexity are still desirable.
